NEW YORK—Markets worldwide swung sharply on June 15, with Wall Street slumping to a big morning loss only to erase all of it within a few hours, as uncertainty weighs about where the economy and the coronavirus pandemic are heading.
The S&P 500 was down as much as 2.5 percent shortly after trading began in New York, following up on even sharper losses in Asia and more moderate ones in Europe. Worries were on the rise that new waves of coronavirus infections around the world could derail the swift economic recovery that Wall Street had seemed sure just a week ago was on the way.
